Abstract

The invention relates to the field of pipeline fluid delivery valves, and discloses a breakaway valve for pipeline fluid delivery control, comprising a first valve tube and a second valve tube, the shapes of the first valve tube and the second valve tube, The size and internal structure are exactly the same, the inside of the first valve tube and the second valve tube are provided with a first chute and a second chute, the first chute communicates with the second chute, and the first chute communicates with the second chute. The second chute is a hexagonal groove, and the inner diameter of the first chute is smaller than the distance between the top and the bottom of the second chute. Through the first valve pipe, the second chute in the second valve pipe is a hexagonal groove, and the passive plate and the moving piston are fitted in the second chute, and the rotating nut fixedly connected to the side of the passive plate is set on the ball screw. The structural design above reduces the closing stroke when the first valve tube and the second valve tube are broken, so that the sealing efficiency is higher when the pipeline is broken.

Description

technical field [0001] The invention relates to the field of pipeline fluid delivery valves, in particular to a breakaway valve used for pipeline fluid delivery control. Background technique [0002] The break-off valve is a commonly used valve body used in pipelines for conveying fluids. It is used to disconnect the pipeline under tension and prevent the leakage of fluid in the pipeline. The break-off valve belongs to the weak connection point of the entire transmission link. The condition is to disconnect the pipeline connection, and the intermediate medium is self-sealing in the pipeline. Most of the existing breakaway valves are bolt-break type. After the breakaway valve is disconnected and separated by the tension of the pipeline, the internal spring is used to push the disc to close. valve port to prevent fluid leakage in the pipeline. [0003] However, when the existing pull-off valve is used, because the valve disc is directly pushed by the spring to close the valve...
